Compare DOC in Java

Our Java SDK is designed to give you the most accurate result, even though comparison is a complex function itself.

Sometimes you need to be sure that the document in the DOC format has not been changed, and if it has, you need to find out what the difference is. Just use our Java diff tool to compare two DOC files and find differences in whole words or single characters. Moreover, if only one character in a word has changed, this word will be marked as changed entirely.

Now you no longer need to spend time manually comparing DOC documents, and you can quickly find even small changes and export such diffs to a document in a convenient format.

Try to compare DOC documents

Check out how our solution to compare DOC files using Java SDK works. To achieve this, load the DOC files you want to compare and select the export file format – it will be automatically loaded after comparing.

Note that you need to accept all revisions in compared documents before calling the comparison method, as shown in our example:

Upload the compared file
Run code
Upload the second file to compare
Select the target format from the list

ApiClient apiClient = new ApiClient("####-####-####-####-####", "##################", null);
WordsApi wordsApi = new WordsApi(apiClient);

String fileName1 = "Input1.doc";
String fileName2 = "Input2.doc";
String fileResult = "Output.doc";

//  Upload documents to cloud storage.
byte[] firstDocumentContent = Files.readAllBytes(Paths.get(fileName1).toAbsolutePath());
UploadFileRequest uploadFirstFileRequest = 
    new UploadFileRequest(firstDocumentContent, fileName1, null);

byte[] secondDocumentContent = Files.readAllBytes(Paths.get(fileName2).toAbsolutePath());
UploadFileRequest uploadSecondFileRequest = 
    new UploadFileRequest(secondDocumentContent, fileName2, null);

//  Compare documents in cloud.
CompareData compareDataOptions = new CompareData();

CompareDocumentRequest compareDocumentRequest = 
    new CompareDocumentRequest(fileName1, compareDataOptions,
	null, null, null, null, null, fileResult, null);

//  Download result document from cloud storage.
DownloadFileRequest downloadFileRequest = new DownloadFileRequest(fileResult, null, null);
byte[] downloadFileResult = wordsApi.downloadFile(downloadFileRequest);
Files.write(Paths.get(fileResult), downloadFileResult.values().iterator().next());
